40 and 100 GB Fiber Optics

Fiber optics uses pulses of light to transmit a signal through tiny “strands” of glass covered in a protective barrier. Because light is less susceptible to degrading factors fiber optics can be ideal for spanning long distances. Every fiber endpoint uses a strand(s) to transmit a signal and a strand(s) to receive a signal. In the case of 40 and 100 GB fiber multiple strands are used to both transmit and receive a signal. This is how 40 and 100 GB “throughput” is achieved with fiber optics.
